Abstract :
An improved quasi two dimensional model, incorporating a depletion-layer approximation, to simulate electrothermal characteristics of a HBT is presented in this paper. In the model the temperature profile and minority carrier distribution are numerically simulated by transmission line matrix (TLM) method. The results show that this model can conveniently simulate the electrothermal effects under the efficient reduction both in CPU time and in memory space
